mappings/VegCSV-VegBIEN.specimens.csv: decimalLatitude/decimalLongitude: Added _nullIf suffix for mergability with VegCSV-VegBIEN.specimens.csv

mappings/VegCSV-VegBIEN.specimens.csv: coordinateUncertaintyInMeters: Added _noCV suffix for mergability with VegCSV-VegBIEN.specimens.csv

mappings/DwC2-VegBIEN.specimens.csv: catalogNumber: Added _if wrapper for mergability with VegCSV-VegBIEN.specimens.csv

mappings/VegCSV-VegBIEN.specimens.csv: catalogNumber direct voucher _if statement: Changed @name to "if indirect voucher", so that it's logical consistent with the else branch following it. It was previously "if direct voucher" because the _if statement only contained a case for direct vouchers, and the else branch was being used in place of a _not() function.

mappings/roots: plots roots: Default to using VegCSV instead of VegX for new plots datasources

mappings/VegCSV-VegBIEN.specimens.csv: catalogNumber _if statements: Changed @names to more descriptive comments. This also prevents the @name from looking confusingly like the condition of the _if statement, which is actually supplied through the cond param and is usually located in a separate mapping.

mappings/VegCSV-VegBIEN.specimens.csv: catalogNumber: Split _if apart into separate _ifs for the indirect and direct voucher cases. Moved direct voucher _if inwards so it is just wrapping catalognumber_dwc itself. This will enable this mapping to be used for specimens data, which is always considered a direct voucher and will always have this _if return true. Also moved indirect voucher _if inwards in the same way, so that a future SQL function implementation of _if only needs to concern itself with returning one value or another, not with handling entire XML subtrees. Note that if the indirect voucher _if returns false, NOT NULL and CHECK constraint violations will cause the intervening voucher and specimenreplicate elements to be deleted, thus having the same effect. Use new @name syntax for distinguishing _if statements.

mappings: Removed no longer used for_review/VegBIEN-DwC2.specimens.csv

xml_func.py: _if(): Changed documentation about name param for distinguishing separate _if statements to use @name attribute instead, so that the XML/SQL function mechanism doesn't have to deal with code that's solely for XPath merging
